Determining whether an object is a member of a collection in VBA

Question

How do I determine whether an object is a member of a collection in VBA?

i used this code to convert array to collection and back to array to remove duplicates, assembled from various posts here (sorry for not giving properly credit).

Function ArrayRemoveDups(MyArray As Variant) As Variant
Dim nFirst As Long, nLast As Long, i As Long
Dim item As Variant, outputArray() As Variant
Dim Coll As New Collection

'Get First and Last Array Positions
nFirst = LBound(MyArray)
nLast = UBound(MyArray)
ReDim arrTemp(nFirst To nLast)
i = nFirst
'convert to collection
For Each item In MyArray
    skipitem = False
    For Each key In Coll
        If key = item Then skipitem = True
    Next
    If skipitem = False Then Coll.Add (item)
Next item
'convert back to array
ReDim outputArray(0 To Coll.Count - 1)
For i = 1 To Coll.Count
    outputArray(i - 1) = Coll.item(i)
Next
ArrayRemoveDups = outputArray
End Function
